- Details
-
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix UMR XLT cleanup on ODP populate failure
mlx5r_umr_update_xlt() allocates and DMA maps an XLT buffer with mlx5r_umr_create_xlt(). The buffer is released by the common cleanup path through mlx5r_umr_unmap_free_xlt().
After mlx5_odp_populate_xlt() became fallible, its error path returned directly and skipped that cleanup. This leaks the XLT DMA mapping and buffer. If the emergency XLT page was used, it also leaves xlt_emergency_page_mutex locked.
Break out of the loop so execution falls through the existing cleanup path.
